Abstract
An air cleaner includes a housing, a filter, a photocatalyst reaction unit which can form spiral a air flow, a forced convection device, and an electrocircuit controller. The forced convection device is located between the filter and the photocatalyst reaction unit. Because the air cleaner uses a longitudinal air conduit, an air inlet along a tangential direction of the air conduit and spiral guide vanes at the inlet, air passing through a fan and into the air conduit flows spirally in the conduct conduit to increase the time during which air contacts the photocatalyst and enables the light of the ultraviolet lamp to radiate the photocatalyst directly so that the cleaning efficiency of the photocatalyst is increased.
Claims5
An air cleaning device with a photocatalyst, comprising:
- a body;
- a filter unit;
- a photocatalyst reaction unit which can generate a spiral air current;
- a forcible convection unit;
- and
- a circuit control unit which can adjustably control operation of the forcible convection unit, wherein;
- the filter unit is disposed below the body and has a front surface with an opening communicating with the outside and a rear surface in communication with the forcible convection unit,
- the forcible convection unit is disposed between the filter unity and the photocatalyst reaction unit so the filter unit communicates with the photocatalyst reaction unit,
- the photocatalyst reaction unit includes an air duct, a photocatalyst coating layer disposed on an interior wall of the air duct, two lamp holders at least one ultra violet ray tube mounted on the two lamp holders, and a blow guide holder on which a spiral blow guide blade is mounted,
- ends of the air duct are hermetically connected to left and right side plates of the body, respectively,
- the air duct includes, at a left side, an air inlet port in communication with air outlet port of the forcible convection unit in a tangential direction thereof, at a right side thereof, and with an air outlet port in a tangential direction thereof,
- ends of each ultra violet ray tube are mounted on the lamp holders and axially disposed inside the air duct, respectively;
- the blow guide holder is located on the left side plate and located at a position of the air inlet port of the air duct, and
- one of the two lamp holder is connected to the right side plate of the body and the other lamp holder is connected to the blow guide holder.
